Abstract
The utility model adopts a technical proposal that a mechanical contact free touch controller consisting of a touch piece, a circuit for converting a human touch signal into an electric signal, a delay circuit, a bistable circuit and a power amplifying circuit. Due to the adoption of the circuit for converting a human touch signal into an electric signal, the mechanical contact free touch controller of the utility model can realize simple control which is a remote control with a single wire. Composed of electronic elements without mechanical contact, the mechanical contact free touch controller produces no electric spark during the control process, which enlarges the application range, and has high reliability and long service life due to no mechanical contact. The mechanical contact free touch controller shows compatibility which contributes to the modification of the power factor of a power grid.
Description
Technical field:
The utility model relates to a kind of touch controller that does not have mechanical contact, and claimed technical scheme belongs to the control apparatus technical field.
Background technology:
Existing controller is a kind of controller that contains mechanical contact---abbreviate the controller of mechanical contact as, its basic composition is: form moving contact, stationary contact by metal, operating mechanism, the shell that arc quenching system and insulating material are formed.Form the controller of mechanical contact because of containing metal, it realize to electrical equipment control the time, produce tangible electric spark, so some occasions as: colliery, chemical plant and gas works etc. can not be used, because that these occasions exist is inflammable, explosion hazard gases, corrosive gas, there is the controller of mechanical contact will produce danger if use.The controller operation circuit complexity that mechanical contact is arranged in addition, the connection lead that the realization far distance controlled needs is many.
The content of invention
In order to solve the defective that proposes in the background technology.The technical solution of the utility model is achieved in that a kind of touch controller that does not have a mechanical contact forms by touching sheet, human body touch conversion of signals electric signal circuit, delay circuit, bistable circuit and power amplification circuit.Touching sheet is connected with human body touch conversion of signals electric signal circuit by lead, human body touch conversion of signals electric signal circuit is connected with delay circuit by lead, delay circuit is connected with bistable circuit by lead, and bistable circuit is connected with power amplification circuit by lead.
The beneficial effect that the utility model and background technology comparison are had is, a kind of touch controller that does not have mechanical contact of the utility model adopts human body touch conversion of signals electric signal circuit, make control of the present utility model simple, can adopt solid conductor to realize far distance controlled.The utility model adopts electronic devices and components to constitute, and does not have mechanical contact, and its control procedure does not have electric spark and produces, and its range of application enlarges, because no mechanical contact so reliability height, the life-span is long.The utility model presents capacitive, helps improving the power factor of electrical network.
Description of drawings:
Fig. 1 is the utility model structured flowchart.
Fig. 2 is the fundamental diagram of the utility model embodiment.
Specific embodiments is as follows:
The principle of work of Fig. 1 is: when the human hand touches the touch sheet, the induced signal of human body is delivered to human body touch conversion of signals electric signal circuit by touching sheet and lead, produce the control electric signal, the control electric signal is delivered to delay circuit by lead, be delivered to bistable circuit by lead again and produce stable switching signal, be high level or low level, switching signal is delivered to power amplification circuit by lead, produce enough big power signal by lead control controlled electric appliance conducting or close.
With embodiment the utility model is further elaborated:
Fig. 2 is the fundamental diagram of the utility model embodiment, and C3, R10 among the figure, D3, VT2, C7 and C4 form one the 220V alternating current is converted to the 9V direct supply, and U2, C9 and C5 form a three-terminal voltage-stabilizing power supply, produce the direct supply of one+5V.CHM is that a metallic touch sheet is received on 3 pin of U1A through resistance R 3, and U1A, C2, R2, C1 and R1 form one and touch switch, and the human-induced signal who touches sheet CHM is converted to a series of square pulse signal U
CP, R4, D1, V1, R5, R6, C8, VC1 and R7 form a delay circuit, and its effect is with a series of square pulse signal U
CPBe converted to open and close signal U
K, U1B forms a bistable circuit, and its effect is with open and close signal U
KBe converted to bistable signal U, R8, D2, V2, R9 and VT1 form a power amplification circuit, and its effect is bistable signal U to be carried out power amplification drive load L, realizes the control to load L.Exemplary embodiment of the present utility model finishes.
